Suby-conversion advice?

Just to chime in on rear mounted rads.
The problem is getting airflow. The factory cars had the advantage of a windtunnel and engineers to calculate flow. You CANNOT guess that a few ducts will be plenty. You CANNOT double the volume of coolant to overcome poor airflow, doesn't help at all.
Mine now works like a charm. What worked for me? Stripping back down to a more basic system in the rear AND adding a small FRONT mounted rad. I waaayyy over engineered the rear trying to compensate for lack of airflow, all sound ideas, agreed upon by others as the thing to do, got worse with every thing I tried... until I added the Boxster rad up front.

Since we're on the topic of Rads (not trying to hiJack this thread), has any of you tried either a water mist system or even NOS for additional cooling ?

Basically you spay water / NOS on the front of the rad, which helps A LOT with cooling. Obviously not something you want to do all the time, but could be something for trackdays etc.

I think it's mostly used for intercoolers but I was wondering if it would also work on a regular rad.
